What is an Excimer Laser?
An excimer laser is a high-precision laser device that uses a mixture of rare gas halides as the gain medium to produce ultraviolet light with extremely short wavelengths. Known for its high energy output and precise control, this type of laser is extensively used in precision material processing and medical applications.
Applications of Excimer Lasers
Excimer lasers are utilized widely in several industries due to their unique properties:
- Semiconductor Manufacturing: Used in lithography processes for miniaturization.
- Ophthalmic Surgery: Such as LASIK, to improve patients' vision.
- Material Processing: Used for drilling, cutting, or marking various materials.
- Scientific Research: Employed in precise measurements and experiments in physics and chemistry.
Reasons to Choose Excimer Laser Repair
- Cost-Effectiveness: Excimer lasers are expensive to purchase and operate. Repairing rather than replacing these devices can significantly reduce costs.
